Referring hv reference eliaraetei-.sv to thisl drawing, the lower sash is'indieatt-l at l and the upper at 2 and eaeh ot' thea von prise-.sl channel shaped harmv or railsv A hai'Y inf: parallel side flanges n and o and an il'iterniediate oppoitely extendingr integral flange formed hy folding;r the nii-tal upon l itself thus making this latter flangeof double thielmess of metal. l The glass pane is indicated at 3 and this is l clamped at its edges between the flanges a2 land the flanges 3* of the angle bars B l which are removably secured to the bars A i hy Screws b. f In order to provide channels of the proper width for the sash guiding ribs 7a of the eover plates of the frame, other angle irons A C are provided which have their flanges r; eorrespomling to the desired channel. The flanges c thas serre as a guide in positionl in;r the angle bars.y being' placed with their edge against the flanges u, or a according to whether the Sash is a lower or an upper one. The flange or web c further Serves the purpose of affording additional metal for l the ei'igagjenient of the threads of the screws b'. The frai'ne hars are initered atthe corners, as indicated in Fig. l, the joints beingr preferably welded and reinforetal by angle pieeex l) fitting in the large channels of the hars and riveted or welded in place.

AS the inner angle iron is not used in Conner.- lion with the meeting rails; l provide strips 11,1 for affording additional inetal to he engaged l| the serews lf'.

Having' thus described my inventionwhat, lelaini iff: l. nietallif: window Saah having side liarS ol' pre sed sheet metal of channel forni.
